In general terms, comp. lit. should be twinked first for some spirit yutto ncu and their treatment bonus.
I had some spare chips in the ql 250ish range though, so I skipped that part and did not go for ql 300s.

The whole thing is not too tricky really, it mostly boils down to getting an acceptable equilibrium between burst and full auto, mostly via str/sta/agi trickle.
I think I used something like this and planted a NW conductor for fa/burst as well.
If one uses higher implants, around ql 231s should be enough to do it without needing a tower.

Got this weapon on at lvl 195. Setup here. Still was about 50 points short on FA and Burst. Dey found me an Omni org that helped with a tower and org contracts, which were just enough to equip the big skawt.
